Abstract

The utility model discloses a low speed permanent magnetic ac generator comprising a housing and a shaft which is penetrated in the center of the housing. A magnet base is fixed on the inner circumferential wall of the housing, and permanent magnets with S poles and N poles arranged alternatively are uniformly distributed on the magnet base. An iron core frame is fixedly arranged on the shaft, pole cores which are corresponding to the permanent magnet are fixed on the iron core frame, and the pole cores are sheathed with coils. The generator has simple structure and the structure of the whole work system is relatively simple; the utility model can generate electricity by using wind-power, hydraulic power, wave, etc. as power.

Description

The low-speed permanent-magnet alternating current generator

The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT).

In the prior art, traditional alternating current generator is in order to obtain the sinusoidal voltage of 50Hz, provide fixed magnetic field by field circuit, working speed is very high, is coupling power at a high speed, often is provided with the speed change and the speed stabilizing system of electromechanical between power source and generator, thereby whole generating system configuration complexity, volume weight is big, and energy utilization rate is low, requires maintenance management person's technical quality height.Just can remove a series of shortcomings that the high speed electricity generation system exists from if can save field circuit and speed change speed stabilizing system, thereby make some conditions relatively poor but the field or the place of low speed power can be provided, obtain electric energy easy to use.

The purpose of this utility model is: a kind of low-speed permanent-magnet alternating current generator is provided, and this generator self structure is simple, and the formation of its overall work system is also fairly simple, and available wind, waterpower, wave etc. generate electricity for power.

One of the technical solution of the utility model is: a kind of low-speed permanent-magnet alternating current generator, comprise shell and the axle that is arranged in the shell center, be fixed with magnet holder on the inner peripheral wall of described shell, be evenly equipped with the S utmost point and N utmost point permanent magnet alternately on the magnet holder, be fixed with the iron core frame on the described axle, be fixed with the pole core corresponding with permanent magnet on the iron core frame, the pole core upper sleeve through has coil.

Two of the technical solution of the utility model is: a kind of low-speed permanent-magnet alternating current generator, comprise shell and the axle that is arranged in the shell center, be fixed with magnet holder on the described axle, be evenly equipped with the S utmost point and N utmost point permanent magnet alternately on the magnet holder, be fixed with the iron core frame on the inner peripheral wall of described shell, be fixed with the pole core corresponding with permanent magnet on the iron core frame, the pole core upper sleeve through has coil.

In two above-mentioned technical schemes, be provided with bearing between described shell and the axle; Described permanent magnet is provided with two row or more than two row, and corresponding pole core also is provided with two row or more than two row.

Advantage of the present utility model is that it is relatively simple for structure, low cost of manufacture, long service life, can change various low speed power into electric energy easily, can effectively utilize wind-force, waterpower, wave to generate electricity.

The utility model will be further described below in conjunction with drawings and Examples:
